First, he should get a medical check up to make sure the weight isn't caused by a health problem. If he is exercising - that really should help. However, the other ingredient to this is to eat less. That is hard to do - but after a few weeks, the stomach shrinks - and he will get full on less. He should eat slowly (most overweight people eat too fast - and they don't have enough time to digest their food - then not knowing when they are actually full). I always say "Think before you put it in your mouth." Are you really hungry? Do you really need it? Are the calories worth it?

great advice there yup now i remember he didnot get a medical checkup,he should hav done it a long time back.........he doesnot have a balanced diet instead he eats lots of junk food rather than.......a balanced diet.......

1. Drink water
Water is quite possibly the single most important catalyst in losing weight and keeping it off longer term.
Water acts as an appetite suppressant by keeping your stomach full and fending off dehydration which can lead to false cravings/hunger.
Water also helps your body metabolize stored fat by helping the kidneys flush out waste. When you don't drink enough water the liver which works to provide stored fat for energy helps the kidneys eliminate waste and becomes less effective at metabolizing fat.
Drinking water ice cold burns about 62 calories a day. Your body has to work to raise that waters temperature to your body's temperature. This equals around 430 calories per week.
2. Eat regularly
This means eating 5 times a day and the most important meal is breakfast.
Make sure you fuel your body first thing in the morning to avoid hunger pangs later in the day.
When you eat 5 times a day you will never feel hungry, make sure the total calories consumed are sensible and don't over eat in any of the meals learn portion size control!
3. Eat lots of fibre
Eating adequate fiber foods to help keep things moving through your bowel. And like water, fiber rich foods bulk you up and make you feel fuller for longer.
Fibre is found only in plant foods our bodies cant digest it to so it simply goes through the body. During the elimination process it cuts calories consumed by attaching to protein and fat that you eat along with it removes that as well
In addition, high fiber foods are typically low in calories and filling, so you are reducing your calorie intake overall.
Good fibre foods include: strawberries, apples, figs, chickpeas, potatoes, (with skins) broccoli, brown rice, beans, bran and nuts.
4. Consume more good fats
There are good fats and bad fats
Good fats provide you with essential fatty acids (linoleic and linolenic acids) needed for normal reproduction and growth, as well as for production of prostoglandin, a hormone like compound that regulates blood pressure, prevents blood clotting and lowers the risk of heart disease.
For example, the reason oily fish is a great food stems from the fact that the essential fatty acids which it contains can actually help your body burn fat more efficiently and protect against disease. Get at least three portions of oily fish a week with Salmon, mackerel, herrings and sardines being good choices. 5. Get plenty of quality protein
Quality protein is an effective weight control tool because of the satiety factor and its ability to keep you full for longer periods. It also balances out carbohydrates by preventing insulin spikes that cause energy loss and sugar cravings
Protein helps to maintain muscle mass which is important in the fat burning process.
Good choices include:
Fish, shrimps, Low fat cottage cheese, low fat yogurt, skimmed milk, egg whites, s Weight gain is caused by consuming too many calories, whether they are from carbohydrate, protein or fat.
6. Carbohydrates can help you lose weight
Don't believe what you read about carbohydrates being bad for you, they can actually help you lose weight!
A diet containing good carbohydrates such fruits and vegetables, wholegrains and moderate in fat and calories, will result in weight loss
Good carbohydrates will also help you combat hunger pangs as they are slowly realized into the body.
When eating carbohydrates eat them "from the earth" with no refining or processing.
These include whole grains, vegetables; fruits and beans.
Sensible weight loss
If you have read the above you will see that it is not the food group, but the quality of the food in it that's important for fast weight loss.

great health routine i will surely tell my friend.....
infact i will post this health routine to my friend the only thing is he should loose weight and look like a person of his age rather than looking older than he is ne is 22 and look like he is in his mid 40s.....

Recommendations for dieting:
Do not eat meat more than once a day. Fish and poultry are recommended instead of red or processed meats.
Avoid frying food because food absorbs the fats from cooking oils and this increases dietary fat intake. Bake or broil food instead. If you do fry, use polyunsaturated oils, such as corn oil.
Include adequate fiber in your diet. Fiber is found in green leafy vegetables, fruit, beans, bran flakes, nuts, root vegetables, and whole grain foods. Fiber often makes you feel full without having to eat excess calories.
Do not eat more than 4 eggs per week. Although they are a good source of protein and low in saturated fat, eggs are very high in cholesterol, and should be eaten in moderation for that reason.
Choose fresh fruit for desserts rather than cookies, cake, or pudding.
Cut down on salt, whether it be table salt, or flavor intensifiers that contain salt such as monosodium glutamate (MSG).
Too much of anything has its drawbacks, whether it be calories, or a particular type of food. A well-balanced diet with creativity and variety are best suited to your needs.
